<h3>What is an expression?</h3>
Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
The solution of the given expression will be:-
E = (3d−3)(d+7)(d−9).
E = ( 3d² + 18d -21 ) ( d- 9 )
E = ( 3d³ + 18d² -21d - 27d² -162 +189 )
E = ( 3d³ + 9d² - 21d + 27 )
Therefore the solution of the given expression will be (3d−3)(d+7)(d−9).
